DAPI Ready Made Solution with Antifade is a glycerol based ready to use solution provided at 1μ
Biochem/physiol Actions
g/mL concentration in a dropper vial that can be applied directly to cells or tissue samples on microscope slides or coverslips. It is recommended to warm up at room temperature and mix by swirling the dropper vial before use. Store DAPI Ready Made Solution with antifade at -20 C protected from light.
Caution
Cell permeable fluorescent minor groove-binding probe for DNA. Binds to the minor groove of double-stranded DNA (preferentially to AT rich DNA), forming a stable complex which fluoresces approximately 20 times greater than DAPI alone.
Footnote
Protects dyes from fading during imaging.
Ready-to-use liquid.
Easy to use Dropper vial application.
Stained sample are stable for longer time period.
Maintains fluorescence signal-little to no quenching.
Immunogen
DAPI, 4′,6-diamidino-2-phenylindole, is a blue fluorescent nucleic acid stain that fluoresces brightly upon selectively binding to the minor groove of double stranded DNA. Its selectivity for DNA and high cell permeability allows efficient staining of nuclei with little background from the cytoplasm. The excitation and emission wavelengths of DAPI-DNA complex are 360 nm and 460 nm, respectively. Most of the fluorescent dyes fade (photobleach) when exposed to excitation light. The amount of photobleaching depends on the composition of the molecule and the time of light exposure. DAPI Ready Made Solution with Antifade is a formulation that suppress photobleaching and prolong fluorescent signals.
